Board Fit and Routing — 1.00 mm Pitch, 12 Positions
This SFW12R-1STE1LF is a 12-position FFC/FPC connector on a 0.039" (1.00 mm) pitch. The right-angle SMT orientation places the mated FFC parallel to the board surface, keeping the z-height to 0.106" (2.70 mm) above the PCB — a tight fit for stacked boards or low-profile enclosures.
Current and Cable — 1 A at 0.30 mm FFC Thickness
For a 12-position cable carrying mixed power and signal, budget the total current across the ground pins. The ZIF (zero insertion force) actuator means the FFC slides in without force on the contacts — the cam locks the cable in place after insertion. This avoids scraping the tin plating on the FFC pads during assembly, preserving contact resistance over the connector's 20 mating cycles.
Mating Cycles and Contact Finish — Tin on Phosphor Bronze
20 mating cycles minimum with tin-plated phosphor bronze contacts. Tin is the economical choice for low-cycle applications — it forms a thin oxide layer that breaks through on the first wipe, but repeated cycling (beyond 20 mates) can wear the plating and expose the base metal, increasing contact resistance. In a product that sees one or two cable swaps over its life, this is fine; for a test fixture or frequent field replacement, a gold-plated sibling would be the better call.
